CARDING-MACHINE Patented Oct. 8, 1907.

Application filed June 18, 1906. Serial No- 822,276.

To all whom it may concern:

Be it known that ROBERT B. ROBINSON, a citizen of the Dominion ofCanada, and EDDO V. BArEs, a citizen of the United States, both residingat Lowell, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Carding-Machines, ofwhich the following is a specification.

This invention relates to machines for carding or straightening thefibers of wool, cotton, or other stock.

It relates to what are known in the trade as reworking cards. Itmay beapplied to the first or second breaker or to the finisher card.

In the drawings, Figure 1 is a diagrammatic side viewleft of themachine, Fig. 1, by feeding in rolls, inter-' mediate, and licker in, inthe usual way. It is carried forward by the swift or main cylinder Bwhich travels at a very high rate of speed, and after being carded as itpasses the workers G D, it is delivered by the fancy C and doffer II,also in the usual way. To arrange our workers in pairs G D, G D, Fig. 1.In this drawing, three pairs are shown but a greater number or a lessnumber of pairs maybe used.

v The teeth of workers G and D are set in the same direction and pointto point with those on main cylinder B, but while worker G revolves inthe same direction as main cylinder B, worker D revolves in the oppositedirection. These workers are arranged to be in carding contact with maincylinder B, but not in carding contact with each other.

Between the workers of each pair is a transfer roll E with teeth setoppositely to those on the workers and arranged to be in cardingcontact, or more properly in stripping contact, with workers G and D andalso with main cylinder B. This transfer roll revolves in the samedirection with worker D and at a somewhat greater surface speed. Thestripper F is located in front of worker G whereby it may be strippedand the stock re placed on main cylinder B. This stripper F revolves ata considerably greater surface speed than worker G, and main cylinder Brevolves at a much greater surface speed than stripper F.

The workers G and D in this construction are not in carding contact witheach other and the transfer roll E is preferably about one half the sizeof workers G and D.

Worker D is the slowest as to surface speed; transfer roll E is somewhatfaster; worker G is considerably faster than transfer roll E; stripper Fis somewhat faster than worker G, and the main cylinder B is very muchfaster than stripper F.

Any suitable arrangement of belts or gears may be used in our machinefor driving the workers, strippers,

and transfer rolls at the required speeds. The trans-v fer roll E may beprovided with straight teeth instead of with the bent teeth of ordinarycard clothing.

In our machine, the stock is carried forward by the main cylinder B andthe first carding takes place between the main cylinder B and the firstworker G. Some of the stock It is carried back from this point by firstworker G and is stripped therefrom by the stripper F and returned to themain cylinder. The rest of the stock is carried forward and is againcarded between the second worker D and the main cylinder B. The cardingat this point between the second worker D and the main cylinder B is themore effective from the fact that the teeth of the second Worker D havebeen cleared by the transfer roll E which acts as a stripper to workerD, before said teeth reach the point of carding proximity with the maincylinder B. Part of this stock is carried along by the main cylinder tothe next pair of workers, and a part S of the stock is forced into theteeth of the second worker D, which have been cleared by the transferroll E and are ready to receive the stock. This stock S is carriedaround by the second worker D until it reaches the point of contact withtransfer roll E by which it is stripped and carried over to the point ofcontact with worker G. As the teeth of the'first worker G have beencleared by stripper F and as worker G travels faster than transfer rollE, the stock S is stripped from transfer roll E and carried along byworker G to its point of carding contact with the main cylinder B. Atthis point, part of this stock S is recarded and the rest is carriedback and stripped by stripper F and replaced on the main cylinder B.

The object of placing transfer roll E in carding or stripping contactwith main cylinder B is to keep the teeth of transfer roll E cleared ofany surplus stock or flyings T which may remain thereon beyond its pointof contact with worker G. This surplus stock and flyings T is more aptto be produced when any of the teeth of worker G get jammed back,straightened, or become bent, broken or clogged with stock from anycause. When such irregularities occur they are taken care of by theteeth of transfer roll E, being cleared by main cyl,

inder B. If the teeth of transfer roll E were not so cleared, by maincylinder B, they might fill up with stock to such an extent as to beuseless. Another ad- 'vantage is that it is more convenient in fittingthe work- I ers and. the transfer roll E and in adjusting them than inother forms of reworking cards.

What I claim as my invention and desire to cover by Letters Patent is,

In a carding-machine, the combination of a main cylinder and a pluralityof sets of rolls cooperating therewith, each set including two workerswhich engage the main cylinder but do not engage each other, a transfer-10 roll of such size and location as to engage both workers and the maincylinder for transferring stock from the second to the first worker, and:1 stripper for taking stock from the first worker and replacing it uponthe main cylinder.

In testimony whereof we :lilix our signatures in presence of twowitnesses.
